FFT is the ultimate FIR filter.

Again, with FFT, which is cheap on modern CPUs, the OP has unlimited 
freedom of experimentation. Creating a bandpass filter is trivial.


"The uniform bins don't play nice with EKG/EEG signals" - why/how ? 
Especially in the context of proposed FIR filters. Anyway, input signal 
can be trivially upsampled, and output signal can be trivially 
downsampled. Upsampling increases number of bins thus improving 
frequency resolution.
